Improvements to Scene System

[x] Make ids case-insensitive
[x] Add more information on when a scene is started (event on failure/func for pre-validation)
[ ] Hotkeys for scene management
[ ] Potential bug related to input enable layers where look controls become disabled whilst free cam controls should be available
[ ] Potential bug where anims marked as hidden cannot be played even when specified exactly via the API.
